In the chemical, oil refining, petrochemical, metallurgical and other industries, the comprehensive utilization of high-efficiency heat exchangers is of great significance to reduce energy consumption, improve the economic efficiency of enterprises, reduce dust, greenhouse gas and acid gas emissions, and achieve "efficient environmental protection".
Heat exchanger is an indispensable equipment for heat exchange and transfer in the process of chemical production. In petroleum, chemical, light industry, pharmaceutical, energy and other industrial production, often use heat exchangers to low-temperature fluid heating or high-temperature fluid cooling, the liquid vaporization into steam or steam condensation into liquid. Heat exchanger can be a unit of equipment, such as heaters, coolers and condensers; can also be a component of a process equipment, such as ammonia synthesis tower heat exchanger.
Heat exchanger is an important unit of chemical production equipment, according to statistics, the tonnage of the heat exchanger accounts for about 20% of the entire process equipment, some even up to 30%, its importance can be imagined.
